Principal Transportation Engineer / Transportation Practice Builder

Are you driven to grow, lead, and make a meaningful impact? At Apex, we’re building more than a consulting and engineering firm—we’re creating a place where your career accelerates, your contributions matter, and your potential is fully realized. We believe your growth is our growth, which is why we invest in your development at every stage of your career. Here, you’ll work on projects that shape communities, protect the environment, and create lasting impact, all while being empowered with the autonomy and flexibility to do your best work.   Fueled by high quality delivery, exceptional client retention, and strategic acquisitions, Apex Companies continues to rank among the fastest-growing firms in the AEC industry, recently recognized by the Zweig Group for our industry-leading growth. Our success is grounded in strong leadership, a collaborative culture, and a shared commitment to delivering exceptional outcomes.   As we continue to grow, we’re focused on building a team of high-performing professionals who are ready to lead, collaborate, and push what’s possible. At Apex, you don’t just join a company, you help shape what comes next.

About the Role

Apex is seeking a senior transportation infrastructure leader to help build and grow our transportation engineering practice in Western Pennsylvania and the broader Mid-Atlantic market. This is not a narrowly defined production role. It is a seller-doer, technical leader, and practice-builder opportunity for a respected transportation professional who can bring credibility with public agency and infrastructure clients, lead complex bridge and roadway work, mentor staff, and help Apex expand its presence in the transportation market.

This role is intended for a senior professional who enjoys staying close to the work while also shaping the business. The right person will serve as a trusted advisor to clients, a senior technical resource to project teams, and a growth partner to Apex leadership. The focus will be on building a durable transportation practice around strong client relationships, high-quality delivery, disciplined project execution, and a team capable of supporting bridge, roadway, drainage, transportation infrastructure, inspection, rehabilitation, and related civil engineering opportunities.

The ideal candidate will bring deep transportation infrastructure experience, strong relationships with agencies and industry partners, and the credibility to help Apex grow from existing civil, water/wastewater, environmental, geotechnical, and infrastructure relationships into a broader transportation platform. This role is especially well-suited for someone who wants the autonomy to build, the support of a national firm, and the opportunity to shape what Apex’s transportation practice becomes in Pennsylvania.

Why This Role Matters

Apex has a strong regional platform, a growing national infrastructure strategy, and an established base of civil, environmental, water, wastewater, geotechnical, and construction-related services. We are looking for a transportation leader who can help connect those capabilities into a stronger, more visible transportation offering.

Success in this role will mean helping Apex:

Build a recognizable transportation engineering presence in Western Pennsylvania and the Mid-Atlantic.

Develop and expand relationships with public agencies, municipalities, transportation authorities, utility/infrastructure owners, and strategic industry partners.

Win and deliver bridge, roadway, multimodal, civil/transportation, inspection, rehabilitation, and infrastructure improvement projects.

Grow a team of engineers, designers, project managers, and technical specialists around practical market opportunities.

Strengthen Apex’s ability to pursue larger and more integrated infrastructure programs by combining local client relationships with national technical resources.

Bring disciplined QA/QC, constructability, project management, and client communication practices to transportation delivery.

Your Responsibilities as a Principal Transportation Engineer

Serve as a senior technical leader and trusted advisor for transportation infrastructure projects, with an emphasis on bridge, roadway, structural, drainage, civil/transportation, and related public infrastructure work.

Help establish, manage, and grow Apex’s transportation engineering practice in the Pittsburgh metro, Western Pennsylvania, and broader Mid-Atlantic market.

Develop and implement a practical growth strategy for transportation services, including target clients, pursuit priorities, teaming relationships, staffing needs, and near-term revenue opportunities.

Lead business development efforts with public and private infrastructure clients, including PennDOT, Pennsylvania Turnpike Commission, counties, municipalities, authorities, and other transportation-related owners or partners, as applicable.

Leverage existing relationships while building new ones to position Apex for transportation engineering, bridge inspection/design/rehabilitation, roadway, drainage, civil/site, and infrastructure planning/design opportunities.

Act as a seller-doer by identifying opportunities, shaping scopes, leading or supporting proposals, developing fees, participating in interviews, and helping convert relationships into backlog.

Serve as Engineer of Record, senior reviewer, technical advisor, project manager, or structural/transportation lead on selected projects, depending on project needs and licensing requirements.

Lead or oversee the preparation of engineering reports, design documents, calculations, construction plans, specifications, cost estimates, technical memoranda, proposal narratives, and client-facing deliverables.

Provide senior QA/QC review for transportation and structural engineering work, including design assumptions, calculations, constructability considerations, risk items, and compliance with applicable agency standards.

Mentor and develop engineers, designers, CAD/BIM staff, project managers, and emerging seller-doers; help create a high-performing technical bench for transportation work.

Recruit, build, and manage or influence a transportation team capable of supporting project execution, client development, and long-term practice growth.

Coordinate with Apex’s civil/site, water/wastewater, stormwater, geotechnical, environmental, construction, survey, and national infrastructure resources to deliver integrated solutions.

Support project managers in managing scope, schedule, budget, quality, risk, change management, subcontractors, and client expectations.

Maintain strong client communication and serve as a senior point of contact for clients, teaming partners, contractors, agencies, and stakeholders.

Participate in industry organizations, conferences, associations, and technical forums to strengthen Apex’s visibility and credibility in the transportation market.

Help create repeatable transportation delivery tools, including proposal language, QA/QC checklists, design standards, client pursuit plans, staffing models, and technical delivery workflows.

Contribute to Apex’s broader One Apex approach by connecting local client intimacy with national resources, specialized expertise, and cross-regional delivery capacity.

What Success Looks Like

You will be successful in this role if you can:

Build a credible transportation infrastructure practice that grows from existing relationships, repeat clients, and strategic new opportunities.

Convert senior market relationships into qualified pursuits, proposals, wins, and profitable backlog.

Serve as both technical leader and commercial leader, balancing client development with project delivery.

Establish Apex as a trusted partner for bridge, roadway, civil/transportation, and infrastructure work in Western Pennsylvania and adjacent markets.

Grow and mentor a team that can deliver high-quality transportation work without relying solely on one senior individual.

Bring practical discipline to delivery: clear scopes, strong QA/QC, sound engineering judgment, schedule awareness, budget accountability, and proactive client communication.

Collaborate across Apex’s national infrastructure, civil, environmental, geotechnical, water/wastewater, and construction teams to create broader solutions for clients.

Help leadership understand where to invest, where to pursue, where to partner, and where Apex can realistically win.
